One of the four temperate seasons that marks the transition of summer into winter is the autumn,somewhere also known as "fall". This season starts around September and continues till November. The word autumn originated from the French word "autompne". This season is called the season of fall because because of the change in color and shedding of the tree leaves. In English literature this season has always been related to the mood of sombre and melancholy. The passing away of summer and the beginning of chilling winter with dull vision of the sky and people turning inward both physically and mentally.
Autumn is the season of harvest. Most ancient cultures featured autumnal celebrations of the harvest,often the most important on their calendars. The celebrations of American Thanksgiving,Jewish Sukkot,Chinese Moon festival take place during the middle of Autumn. There are also the many North American Indian festivals tied to harvest of autumnally ripe foods gathered in the wild. The predominant mood of these autumnal celebrations is a gladness for the fruits of the earth mixed with a certain melancholy linked to the imminent arrival of harsh weather. In North America, autumn is also associated with the Halloween season which in turn was influenced by Samhain,a Celtic autumn festival and with it a widespread marketing campaign that promotes it.
